Application-lune 18, 1941, Serial No. 398,596 2 filaimsl (01. 22-65) (Granted under the act of rch 3, 1883, as

amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates to centrifugal casting molds and in particular to an adapter for accommodating a pouring spout.

In centrifugal casting it is usual to provide a face plate with a central opening on the pouring end of the cylindrical mold which serves the double purpose of retaining the spinning metal in the mold and of centering the pouring spout. It permits the use of a small pouring spout and adapters may be interchanged to accommodate different sizes of pouring spouts. Likewise its removabilityfacilitates removal of the finished casting from the mold.

With respect to theneed for a strong, tight union between adapter and mold, together with ready removability it has been found that a wedge pin coupling serves the dual purpose admirably and further, that if the adapter face is dished out with a slope complementary to that of the wedge pins, a more extensive and hence more eflicient contact is made.

It is therefore an object of this invention to provided an adapter for a centrifugal casting mold which shall furnish a firm and reliable coupling therewith and be capable of easy removal.

The specific nature of the'invention as well as other objects and advantages thereof will clearly bular, portion 5 loosely fitted within the mold I, and a flanged portion 6 engaging the face of the mold. Flange 6 has openings which are slipped over studs 1 threaded into the mold and the studs 1 have slots for reception of wedges 8 in front of the flange 5. The front face of the adapter is dished as at'9 with a slope complementary to the wedges 8 so that a maximum of pressure surface is engaged and a more extensive and uniform distribution of stresses is obtained. This will facilitate assembly and removal and lengthen the I useful life of the various units in the assembly.

appear from a description of a preferred embodiment as shown in the accompanying drawing in which the figure shows an elevational view in axial section of the the adapter in place.

Referring to the drawing 'by characters of reference, there is shown a tubular mold I having a flange '2 for attachment to adriving rotor 3 by means of bolts 6. The adapter comprises a tupouring end of a mold with Since the wedges are inserted from the axis outward, centrifugal action will tend to maintain them in locking p'osition, although it will be understood that the wedges may be directed inward and the sloped face of the adapter may be convex rather than concave.

A portion of the pouring spout I0 is shown in place within the adapter.

I claim:

1. In a centrifugal casting machine, a tubular mold, and an adapter for reception of a pouring spout applied to a face of said mold, openings in the adapter, means on the face of the mold passing through said openings respectively, slots in said means outside the adapter, wedges in said slots, and a slant surface on the outer face of said adapter of a slope complementary to that of slots, and a dished surface on the outer face of said adapter of a slope complementary to that of- .the wedges.
